Stable water-in-oil emulsion membranes can be prepared using [dilauryl(dimethyl)ammonium] bromide (DDAB), a cationic surfactant. We prepared ultrasmall cyclodextrin (γ-CyD) nanogels (γ-CyDngs) by forming ionic pairs between the secondary hydroxyl groups of γ-CyDs and DDAB. Fluorescence and NMR characterisation of the obtained γ-CyDngs revealed superior inclusion affinities compared with native γ-CyDs, beneficial for the solubilisation of hydrophobic compounds in water.
可以使用阳离子表面活性剂[二月桂基（二甲基）溴化铵]（DDAB）制备稳定的油包水乳液膜。我们通过在γ-环糊精（γ-CyD）的仲羟基与DDAB之间形成离子对来制备超小环糊精（γ-CyD）纳米凝胶（γ-CyDngs）。对所得γ-CyDngs的荧光和核磁共振表征显示，与天然γ-CyDs相比，其具有更高的包合亲和力，这有利于疏水性化合物在水中的增溶。
